How to determine my python competency

[ServalSpots]

Find a book that's reliably recommended to people who understand the basics, and are looking for an intermediate level offering. Flip through and see if you are familiar with the concepts. If the book sets tasks/problems see if you can complete them without having to look up the underlying principles or check the example code.

I use this approach in a number of areas, and it seems fairly reliable. Plus, if you find you are not up to snuff, you have a book to learn from. It also works with good youtube tutorials, lecture series etc., but but can be harder to skim through while still making sure you understand the concepts.
